EDMUND LANDIS, or LANoAsTEarENNsYLvANIA.

'muss Specification of Letters Patent No. 2,829, dated October 22,1842.-Y

To all whom t may concern Y Y which- Be it known that I, EDMUND LANDis,of the city and county of Lancaster, in the `State of Pennsylvania, haveinvented anew and useful Improvement in Dresses for the More EectualRelief and Cure of the Disease called Hernia; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, making a part of thisspecicatio-n, in

Figure l, is a' perspective view; Fig. 2,

blocks detached; Fig. 3, geometrical top lan.

The nature of my invention consists, in the addition of a slight springor springs to the main spring of a truss which passes around the body ashereafter described.

The main spring A is formed of steel,` of

suitable dimensions for the purpose required, and is so constructed asto extend horizontally around the body from the extreme end of theSpino-us processes of the lumbar vertebra, across the spine, aroundlandacross the abdomen nearly'to the inguinal canalof the side on which itcommenced; it is bent to lit thebody as nearly as practicable, and onits anterior end a button (a) is attached to fasten the strap to, as inthe commontruss. To the spring AI affix another spring B, of the samewidth, and about one third its length extending from the ante-` rior endof the spring A, back along its inner face, the other end of the springBV, being its point of attachment; this spring is about one half thestrength of A, it being made thinner.

To the loose end of spring B I attach an iron (b) about 2 inches longAmore Vor less, flattened atA each end, and contracted at the center, theend which is riveted tothe spring is of the same form as the end ofthe`Vspring and about twice its thickness the other end is formed to t theblock and holdv it steady, and to it the block is screwed. The blockshould be of the proper form to tthe parts f as the nature of the caserequires. Fora double rupture consisting of a descending hernia onboth-s1des,'aspr1ng' (c). oftthe sameJ width and thickness as spring B,is at Y tached Vto that spring, :just-behind the end of theA iron (b)this spring extends baclron the inside of 'spring B, about t-Wo fths itslength, nearV the loose en'd of C. A long-iitudinal slot (c) is made forthe purpose of D, to; the end of this iron whichis attached to thespring C, is' somewhat longer than the iron b, otherwise itis similar inform-g twoscrews (e, e,) pass thro-ugh theslot (c) Aattaching an iron(0') Ythatholds the block into the iron (c) and conne it theretogvby ythis construction the block D, is made to appreach or recede from theother block as desired. By the elasticity and independent action ofthesprings B andC, the blocks ture Vduring the most varied, motions' 'ofthe body, in a simple and eh'icient manner, and a,

speedy and permanent cure is thus eected.

What I claim as my invention and" desire 'to secure by Letters Patentis- Vl. The combination of the 'long slender spring B, with the mainspring A, of Vthe truss to maintain an equal pressure on the ruptureduring-.every motion of the body, in'

the manner and for the purpose herein set forth. Y.

Y are keptequably vand firmly against the rup- 2.V I also claim incombination with: the

above springs Aand B the spring C, ad-

justed by screw (f) constructed and varranged as abo-ve described.

3. I further claim the combination lof the blocks placed obliquely onthe abdomen over the inguinal canal with the horizontal spring forgiving a perpendicular Vpressiff'e 'upon the part-sfeected-as abovespeciiiedn,E
